阅读下面文字,回答问题。

我们要了解和评判一个作者,应该知道他那时代对于他那一类作品的意见,这些意见就是后世文艺批评史的材料,而在当时表示一种文艺风气。一个艺术家总在某些社会条件下创作,也总在某种文艺风气里创作。这个风气影响到他对题材、体裁、风格的去取,给予他以机会,同时也限制了他的范围。就是抗拒这个风气的人也受到它负面的支配,因为他不得不另出手眼来逃避或矫正他所厌恶的风气。正像列许登堡所说,模仿有正有负,亦步亦趋是模仿,"反其道以行也是模仿";圣佩韦也说,尽管一个人要推开自己所处的时代,仍然免不了和它接触,而且接触得很着实。所以,风气是创作里的潜势力,是作品的背景,而从作品本身不一定看得清楚。我们阅读当时人所信奉的理论,看他们对具体作品的褒贬好恶,树立什么标准,提出什么要求,就容易了解作者周遭的风气究竟是怎么一回事,好比从飞沙、麦浪、波纹里看出了风的姿态。

一时期的风气经过长时期而能保持,没有根本的变动,那就是传统。传统有惰性,不肯变,而事物的演化又使它不得不以变应变,于是产生了一个相反相成的现象。传统不肯变,因此惰性形成习惯,习惯升为规律,把常然作为当然和必然。传统不得不变,因此规律、习惯不断地相机破例,实际上作出种种妥协,来迁就事物的演变。它把规律解释得宽,可以收容新风气,免得因对抗而摇动地位。传统愈悠久,妥协愈悠久,妥协愈多,愈不肯变,变的需要就愈迫切,不再能委曲求全,于是旧传统和新风气破裂而被它破坏。新风气的代兴也常有一个相反相成的现象。它一方面强调自己是崭新的东西,和不相容的原有传统立异;而另一方面要表示自己大有来头,非同小可,向古代另找一个传统作为渊源所自。例如明、清的批注家要把《水浒》、《儒林外史》等白话小说和《史记》、《汉书》挂钩搭线,西方十七、十八世纪批评家也要把新兴的长篇散文小说遥承古希腊、罗马的史诗。这类暴发户造谱牒或者野孩子认父亲的事例,在文学史上常有;它会影响创作,使作品从自然的天真转而为自觉的有教养、有师承,所以未可忽视。(节自钱钟书《中国诗与中国画》)

     Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of

spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach.

Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many

people's diets. Even some children who hated the taste began to eat the vegetable.

     Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does

not have any more iron than any other green vegetable.

     People only thought spinach had a lot of iron because the people who studied the food made a

mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that

spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted

it.

     Today, we know that the little iron there is in spinach cannot make a difference in how strong a person

is. However, spinach does have something else which the body needs-folic acid.

It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic

acid that made Popeye strong all along.
